7 Ways to Properly Maintain Your Metal Roof

Maintaining a metal roof is crucial for maximizing its lifespan and ensuring it remains functional and aesthetically pleasing. Metal roofs are renowned for their durability, energy efficiency, and resistance to severe weather conditions. However, you can further extend the life of your metal roof and maximize it's performance with these essential tips:

1. Regular Inspections

Regular inspections are the cornerstone of effective roof maintenance. It's advisable to inspect your metal roof at least twice a year—typically in the spring and fall. This is a simple ground inspection, no need to get on the roof. Look for any signs of damage, such as scratches, dents, etc. Also, check for sealant failures around the edges and at the joints. If you live in an area prone to severe weather, consider additional inspections after significant events like heavy storms or snowfalls.

2. Clean Debris Regularly

Leaves, twigs, and other debris can accumulate on your roof, especially if there are overhanging branches. This accumulation can retain moisture, leading to corrosion over time. Clean your roof regularly by gently using a soft broom or brush to remove debris. Avoid using a power washer as the high pressure can damage the protective coatings on the metal.

3. Manage Overhanging Branches

Overhanging branches not only drop debris but can also scratch the surface of your roof during windy conditions. Trim any branches that hang too close to your roof to minimize physical damage and reduce the accumulation of organic materials.

4. Ensure Proper Drainage

The gutter system plays a vital role in protecting your roof by channeling water away from the structure. Make sure your gutters and downspouts are free of debris to prevent water backup, which can lead to roof damage. Check for signs of sagging or leaks in your gutter system and repair them promptly.

5. Fix Fasteners and Sealants

Metal roofs expand and contract with temperature changes. Over time, this can lead to loosened fasteners and deteriorated sealants. During your regular inspections, check for these issues. Tighten any loose screws and replace old or damaged sealants to maintain the integrity of your roof. For aging metal roofs, you may even consider a screw replacement.

6. Look Out for Scratches and Scuffs

Minor scratches and scuffs can often be repaired with manufacturer provided touch-up paint. However, it’s essential to use products recommended by the roof manufacturer to ensure compatibility with the existing coating and to maintain the warranty.

7. Professional Maintenance

While many aspects of metal roof maintenance can be handled by homeowners, some tasks might require professional expertise, especially if your roof is hard to access or if major issues are found. Hiring professionals ensures that repairs are done safely and effectively.


Proper maintenance will not only extend the life of your metal roof but also help preserve its appearance and functionality. By conducting regular inspections, promptly addressing any damage, and ensuring that the roof is clean and free from debris, you can enjoy the full benefits of having a metal roof for many years. Remember, the cost of regular upkeep is minimal compared to the expense of repairing or replacing a neglected roof.
